CVE-2014-1651 - CWE-89: Improper Neutralization of Special Elements used in an SQL Command
Symantec Web Gateway 5.1.1.24, and possibly earlier versions, contains a SQL injection vulnerability in the hostname parameter of the clientreport.php page.

Impact

A remote unauthenticated attacker may be able to inject arbitrary script or SQL commands.

Solution

Apply an Update

Symantec Web Gateway users should upgrade to 5.2.1 or later. Users can click “Check for Updates” on the Administration->Updates page to receive the fixed version. If you are unable to upgrade, please consider the following workaround.

Restrict Access

As a general good security practice, only allow connections from trusted hosts and networks. Note that restricting access does not prevent XSS or SQLi attacks since the attack comes as a request from a legitimate user's host. Restricting access would prevent an attacker from accessing the web interface using stolen credentials from a blocked network location.
